Volleyball Competition on Consecutive Days Modifies Jump Kinetics but Not Height.

Purpose: In volleyball, jump execution is critical for the match outcome. Game-play-related neuromuscular impairments may manifest as decreased jump height (JH) or increased jump total duration, both of which are pivotal for performance. To investigate changes in JH and kinetics with game play, the authors conducted a prospective exploratory analysis using minimal-effect testing (MET) and equivalence testing with the 2 one-sided tests procedure, univariate, and bivariate functional principal component analysis, respectively.

Using the VERT wearable device to monitor jumping loads in elite volleyball athletes.

Sport is becoming increasingly competitive and athletes are being exposed to greater physical demands, leaving them prone to injuries. Monitoring athletes with the use of wearable technology could provide a way to potentially manage training and competition loads and reduce injuries. One such technology is the VERT inertial measurement unit, a commercially available discrete wearable device containing a 3-axis accelerometer, 3-axis gyroscope and 3-axis magnetometer.

"To Tech or Not to Tech?" A Critical Decision-Making Framework for Implementing Technology in Sport.

The current technological age has created exponential growth in the availability of technology and data in every industry, including sport. It is tempting to get caught up in the excitement of purchasing and implementing technology, but technology has a potential dark side that warrants consideration. Before investing in technology, it is imperative to consider the potential roadblocks, including its limitations and the contextual challenges that compromise implementation in a specific environment.

The Effect of Injury Definition and Surveillance Methodology on Measures of Injury Occurrence and Burden in Elite Volleyball.

A time-loss injury definition continues to be the most widely used injury definition despite evidence that it fails to accurately capture overuse injuries. An overuse injury questionnaire, using an "all complaints" definition has been created to address the limitation of a time-loss definition. The main aim of this work was to determine the effect that injury definition and registration methodology has on the collection of knee injuries among elite level volleyball players.

Methods: A systematic search of MEDLINE, Embase, AgeLine and Cochrane library for cohort studies was conducted.

Results: Eleven studies (n=5733 patients) met the inclusion criteria.

Validation of an inertial measurement unit for the measurement of jump count and height.

Objectives: To validate the use of an inertial measurement unit (IMU) for the collection of total jump count and assess the validity of an IMU for the measurement of jump height against 3-D motion analysis.

Design: Cross sectional validation study.

Setting: 3D motion-capture laboratory and field based settings.

Dipeptidyl Peptidase-4 Inhibitors in Chronic Kidney Disease: A Systematic Review of Randomized Clinical Trials.

Background: Chronic kidney disease (CKD) is common in patients with type 2 diabetes mellitus (T2DM) and limits therapeutic options. Dipeptidyl peptidase-4 (DPP-4) inhibitors represent a novel class of oral glucose-lowering agents and are known to be safe and effective in the general population.

Methods: We searched Cochrane, EMBASE, and PubMed from the time of their inception until March 2015.

Honoring Our Hospital's History: A Preservation and Digitization Initiative.

There is limited literature on hospital archives projects. Hospitals understandably have a strong focus on patient care, but there is still a critical need to keep institutional archives. Among their many uses, institutional archives preserve corporate memory, provide evidence of interactions with community, and assist in contemporary decision making.

Long-Term Effects of Postoperative Delirium in Patients Undergoing Cardiac Operation: A Systematic Review.

Delirium is an acute syndrome that involves fluctuating changes in attention and cognition. Although delirium is the most common neurologic complication after cardiac operation, data about its impact on long-term outcomes are lacking. The purpose of this systematic review was to examine the effect of postoperative delirium (PoD) on long-term outcomes, including morbidity, probability of death, cognitive decline, institutionalization, and health-related quality of life (HRQoL) in patients undergoing cardiac operation.

The Effect of Erythropoietin-Stimulating Agents on Health-Related Quality of Life in Anemia of Chronic Kidney Disease: A Systematic Review and Meta-analysis.

Background: The efficacy of erythropoietin-stimulating agents (ESAs) for improving health-related quality of life (HRQOL) in anemia of chronic kidney disease (CKD) is unclear.

Purpose: To determine the effect of ESAs on HRQOL at different hemoglobin targets in adults with CKD who were receiving or not receiving dialysis.

Data Sources: Searches of PubMed, EMBASE, the Cochrane Library, and ClinicalTrials.

Urinary, Plasma, and Serum Biomarkers' Utility for Predicting Acute Kidney Injury Associated With Cardiac Surgery in Adults: A Meta-analysis.

Background: Early accurate detection of acute kidney injury (AKI) occurring after cardiac surgery may improve morbidity and mortality. Although several novel biomarkers have been developed for the early detection of AKI, their clinical utility in the critical intraoperative and immediate postoperative period remains unclear.

Study Design: Systematic review and meta-analysis.

The cost effectiveness of erythropoietin-stimulating agents for treating anemia in patients on dialysis: a systematic review.

Background: Anemia is a common complication associated with kidney failure and is marked by poor health and increased risk of morbidity and mortality. There are ongoing concerns with the use of Erythropoietin Stimulating Agents (ESAs) to treat anemia in patients with kidney failure on dialysis. Questions as to their benefits, harms and overall effect on quality of life are still relevant today.

The diagnostic accuracy of tests for latent tuberculosis infection in hemodialysis patients: a systematic review and meta-analysis.

Background: Reactivation of latent Mycobacterium tuberculosis infection is an important health concern for patients on hemodialysis because of their immunosuppressed state and in kidney transplant patients receiving immunosuppressive therapy to prevent organ rejection. There are several tests available to determine the presence of latent tuberculosis infection: the tuberculin skin test (TST), QuantiFERON-TB Gold (QFT-G), and T-SPOT.TB.
